FAQ

We have organized several common questions for our clients，may help you sincerely：

What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

Can you tell me the parameter of your solar cells?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Can you do OEM for us?

Yes, we can.

How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The perfect time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Brief introduction of Monocrystal Solar Energy Cell

Silicon rods, materials performance indicators in order to reduce production costs, and now terrestrial applications such as solar cells using solar grade somewhat relaxed. Some also use semiconductor device processing materials and discard the head and tail of silicon materials, solar cells drawn into complex dedicated silicon rods.The silicon rods cut into pieces, usually 0.3 mm thick sheet. Processing solar cells, the first doping and diffusion in silicon, a trace amount of dopant is generally boron, phosphorus, and antimony. Diffusion is carried out in a quartz tube into a high-temperature diffusion furnace. Thus formed P> N junction on the wafer. Then using a screen printing method, fine with a good paste into a grid line printed on the wafer, after sintering, while forming the back electrode and the surface coated with antireflection gate line source to prevent a large number of photons it is reflected off the smooth surface of the wafer. Thus, the monomer Monocrystal solar energy cells are produced. After single-chip random testing can be assembled according to the required specifications into a solar cell module (solar panel) by the method of series and parallel to a certain output voltage and current.

Polycrystalline silicon solar cells and Monocrystal solar energy cells is no different. Life and stability of polycrystalline silicon solar cells and Monocrystal solar energy cells are good. Although the average conversion efficiency of silicon solar cells is higher than the average conversion efficiency of polycrystalline silicon solar cells of about 1%, but because of Monocrystal solar energy cells can be made quasi-square (four to the top of the arc), when the composition of the solar cell module when there is a part of the area filled up, and polycrystalline silicon solar cells are square, there is no problem, so the efficiency of the solar cell module is the same.In addition, because the manufacturing process two types of solar cell materials is not the same, polycrystalline silicon solar cell manufacturing process energy consumed than Monocrystal solar energy cells is about 30% less.

Q:Anybody ever heard of thin film solar cell? What it that?

From the information I got from wikipedia, A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal.

Q:Can somebody list some of the materials used for making solar cells?

There are quite many materials to make a solar cell, but silicon is something you need to have.

Q:Can solar panels be charged with light?

Since the output power of solar modules depends on factors such as solar irradiance and solar cell temperature, it is not recommended to use light charging, efficiency is not only very low, and also meaningless.

Q:What can be used as the materials for solar cells?

TPT

Q:How long does it take to make a solar cell?

Solar cell requires the sunlight to be made eventually, so if it's not sunny at all, it will take you much longer than you thought.

Q:What is the right way to operate a solar cell?

Solar cells convert light energy into electrical energy either indirectly by first converting it into heat, or through a direct process known as the photovoltaic effect.

Q:Why and what is the low efficiency solar cell?

I do know when the energy is absorbed by the solar cell, there will be loss in the conversion, that is one of the reason that the solar cell becomes low efficient.

Q:Is A grade better than the B grade when we buy the poly solar cells.

I think the A grade is better than B grade, but just not sure how better it can be compared to the others.

Q:The difference between a fuel cell and a solar cell

At present fuel cell system fuel - power conversion efficiency of 45% to 60%, while the thermal power and nuclear power efficiency of about 30% to 40%. (2) Hazardous gases SOx, NOx and noise emissions are low CO2 emissions are greatly reduced due to high energy conversion efficiency, no mechanical vibration.

Q:Why is the solar cell produced by DC

The key is to have a magnetic field change. Of course, there is no solar energy. There are only energy changes.
